AGR — Pisum sativum

Summary

PSAT1G142280 (AGR, also known as PIN2) on garden pea chromosome 1LG6 encodes an auxin efflux carrier of the PIN-like family, with annotated auxin efflux transmembrane transporter activity and multiple phosphoinositide-binding capacities. The gene is associated with basipetal and acropetal auxin transport, regulation of cell polarization, differential growth, and anthocyanin accumulation in response to UV light. It is linked to gravity response, phototropism, root and shoot architecture traits including lateral root length, root hair length, shoot branching, leaf morphology, and water use efficiency. Associations also include brassinosteroid content and sensitivity, ethylene sensitivity, osmotic response sensitivity, stomatal resistance, stem senescence, and plant stress response. Related genes in other species are linked to gravitropic root growth, polar subcellular localization, auxin efflux, and salt tolerance.
